All right, so what is a hairpin? so a hairpin is a type of secondary structure found only in single strands of nucleotides.
00:10
Okay, so this is not going to appear on a double -stranded dna molecule.
00:14
This is only going to occur on single -stranded nucleotide or polynucleotide strands.
00:22
So i'm going to look at mrn, which is just rna after it has been copied from a dna.
00:30
Strand.
00:32
So it's going to be single -stranded.
00:34
And the formation of hairpins happens when the sequences of nucleotides on the single strand are inverted complementary repeats of one another.
00:43
So we'll just do something really simple.
00:46
So we will do right here.
00:49
So let's say this is a, this is g, and this is c.
00:55
So an inverted complementary repeat.
00:58
So let's say, you know, there's more strands here, here, here, more bases.
01:07
And then right here is going to be an inveted complementary repeat.
01:11
So g is going to be g.
01:15
It's going to be inverted.
01:17
G .c...
